The new Mastersizer 3000 particle size analyser delivers rapid, precise particle size distributions for both wet and dry dispersions. Working over the millimetre, micrometre and nanometre particle size ranges, it packs exceptional performance into the smallest of footprints, bringing operator-independent measurements that every user can rely on.
Broad measurement range:
from 10 nm to 3.5 mm with exceptional resolution in the sub-micron range.
High data acquisition rates
Reproducible, accurate measurement: data acquisition rates of 10 kHz increase reproducibility and ensure accuracy even for materials with the broadest size distributions.
optical bench spans just 690mm. Smart design of the new optical core packs this high performance into a small footprint system that boasts equally well-engineered sample dispersion accessories, including an entirely novel dry powder dispersion unit.

Using the Aero S the Mastersizer 3000 measures the particle size of even friable dry powders
Equipped with the novel Aero dry dispersion unit, the Mastersizer 3000 now extends dry measurement to the widest possible range of sample types. The design of the Aero reflects state-of-the-art dry powder dispersion knowledge and enables users to measure materials from cement to coffee, cohesive minerals to fragile pharmaceuticals, from 0.1 micron up to 3.5 mm in the dry state. Rapid and efficient, this new dispersion unit is supported by the fastest data acquisition rates available. Dry measurements become stable more quickly, and even challenging samples with very wide size distributions are measured accurately.
Dry dispersion of powders is a fast, intuitively appealing and environmentally neutral (no requirement for the disposal of liquid dispersants) approach to sample preparation for laser diffraction particle sizing. However, its application to fragile, friable particles is constrained by the need to apply enough energy for dispersion without breaking or milling the sample.
To accommodate this, Aero has been designed from the ground up, taking account of the latest dry powder dispersion theory. The modular dispersion venturi system means that the user can easily select the most appropriate dispersion mechanism for their samples. The standard venturi supplied with the Aero is suitable for a very wide range of samples, dispersing even moderately cohesive materials while maintaining the integrity of fragile particles. An optional venturi, which disperses the sample with a direct impaction mechanism, can be used for more aggressive break up of agglomerates and highly cohesive materials.
Sensitive pressure control to within +/-0.1 bar across the range 0.1 to 4 bar, allows precise tailoring of energy input to meet diverse sample requirements. The smooth and efficient sample feed means you can rely on the measurements to be robust. There are different feed trays and hoppers to accommodate various sample sizes, while an enclosed cell ensures bias-free measurement and minimizes user exposure.
